Original Filed March 7, 1931 TURN BY* %INVIENTDR- MM it, is, 1933 I numb STATES PATENT DEERE owns a. aonmsom'or wnmLma-wnsr vmomm, assrouon 'ro wmnme arm coaroaarron, or wnmmmo, wns'r vmomu, A oonroaa'rronor manalpplicaflon fled larch 7, 1931, serial This invention relates broadly to sheet metal containers, and more specifically to a container of so-called dual ty The primary object of the inventlon 1s to provide a simple and improved. form of dual As is well understood, certain kinds of materials, as, for instance, paints having an aluminum base, are not adapted to be furnished in read-mixed form, due to the fact that the base material, or pigment, not onl fails to remain in suspension in the. liqui vehicle, but tends to become solidified on the bottom of the container to the extent that suhsequent agitation or stirring for efiectin even distribution thereof is rendered excee ingly dificnlt, it not actually practically impossihle of attainment b means readily availshle to the average u timate user.

Therefore, as hereinbefore indicated, it is an object of the invention to provide a drum or cash of dual type adapted for-use as a container for paint materials and wherein the liquid vehicle and the pi out, the latter being ordinarily provide in dry powder or granular form, are maintained se arate and apart, each from the other, until mixture thereof preparatory to immediate use is re quired.

A further object is to provide an outer drum-like container having removably mounted or nested within an end thereof a second, or auxiliary, container and provided with a removable closure by means of which leak-proof seals areformed with both of said containers.

In describing the invention in detail, reference is herein had to the accompanying drawing, in which- Figure 1 is a partial vertical section of the invention; and- Fi re 2 is an enlarged detail section showing t e seals formed between the closure and .each of the two containers Referring to said drawing, 1 designates the body of an outer sheet metal receptacle or container of drum-like form having about its terminal in non. comm no. new. Renewed ember '4, 1932.

inwardly directe annular rib 4, and removably mounted in more or less closel tele= scoped or nested position within sai body and having the bottom chime portion 5 thereof resting upon said seat 3 is a second sheet metal receptacle'or container Ii,

The receptacle 6 has at its upper end an inwardly turned annular terminal roll or head 7 which, in the nested position indicated, is located at a suitably spaced short distance below the level oi the top surface or. the rim roll 2, as shown The receptacle 1 is designed to contain within the lower portion thereof, or in the space below the bottom of the receptacle ti, liquid paint vehicle, as an oil, while the said vessel 6 constitutes a container for the pigment base which, in the preparation of the Eli paint for use, is subsequently to be mixed m with said vehicle.

Removably mounted in closing relation to the two vessels 1 and 6 is a cover 8 having an outwardly turned annular rim 9 of down@ wardly facing channel form, and mounted in the channel thereof is a readily compressible gasket 10, preferably in the form of a rule ber tube, designed to seat upon and form seal with the rim r0112 of the drum. Spaced 11 formed integral with and depending rom the rim 9 of the cover are designed to be turned into underlying seated relation to the rim roll 2 for securing the cover in its seated position.

The rim 9 occupies elevated relation to the body of the cover, as shown, and located at a suitable level below said rim is a downwardly facing shoulder 12 formed by the provision in said cover body of an angular ofiset 13. Said shoulder constitutes a seat upon which is carried a gasket 14 adapted, in the seated position of the cover, to rest upon and form a seal with the terminal roll 7 of the inner container 6.

The inwardly directed terminal roll 7 not only serves as a seat for the shoulder 12 of rim located below the level of the rim of saidouter receptacle, and a cover removably mounted in seated relation to and forming a seal with both of said rims.

2. A dual container comprising an outer receptacle having at an end thereof an outwardly turned rim and having intermediate its ends an internal annular seat, a receptacle nested within said outer receptacle and supported by said seat, the inner receptacle having a rim located below the level of and in wardly with respect to the rim of said outer re'ce tacle, and a cover removably mounted in closmg relation to both of said receptacles", said cover having a rim occupying overlying attached relation to the rim of said outer receptacle and having an ofi et shoulder seated on the rim of the inner receptacle.

3. A dual container comprising an.outer receptacle having at an end thereof an outwardly turned rim and having intermediate its ends an internal annular seat, a receptacle nested within said outer receptacle and having the outer annular edge portion of its bottom resting upon said seat, the inner recepta cle having an inwardly turned rim located below the level of the rim of said outer receptacle, and a cover removably mounted in seated closing relation to both of said receptacles, said cover having a gasket-carrying rrim overlying and attached to the rim of said outer receptacle and also having therein an offset gasket-carrying shoulder seated upon the rim of said inner receptacle.

4. A dual container comprising an outer receptacle having at an end thereof an outwardly turned rim and having intermediate its ends an internal annular seat, a receptacle nested within said outer receptacle and supported by said seat, the inner receptacle having an inwardly turned rim located below the level of the rim of said outer receptacle, and a cover removably mounted in seated closing relation to both of said receptacles, said cover having a rim portion providing a downwardly-facing channel within which the rim of said outer receptacle is received, said cover also having therein an ofi'set gasket-carrying shoulder rest-ing upon and forming a seal with the rim of said inner receptacle.

5. A dual container comprising an outer receptacle having an inwagdly bent rib spaced neoaeae from the top thereof, an inner receptacle supfrom the top thereof, an auxiliary drum nest-- ed in the outer drum and restingagainst said rib, a cover for the container, and sealing means for preventing leakage past said cover from either the outer or the auxiliary drum.

8. A dual container comprising an outer receptacle having an internal rib, spaced from the top thereof and a rolled upper edge, an inner receptacle positioned with the outer receptacle by said rib and having a rolled upper edge, a cover closing the container, and sealing means cooperating with said rolled upper edges for preventing leakage.

9. A dual container comprising an outer drum having a rolled upper edge, an auxiliary drum nested in the outer drum and havmg a rolled upper edge, a cover for the container, and a pair of gaskets, one interposed between each rolled edge and the cover for sealing the drums.

10. A dual container comprising an outer receptacle having formed integrally therewith a support, an inner receptacle within the outer receptacle resting against said. support,-a cover closing the outer receptacle, and sealing means for preventing leakage from one receptacle" to the other.

11. A dual container comprising an outer drum having a stop spaced from the top thereof and shaped from the material of the drum, an inner drum positioned in the outer drum by said stop, said inner drum having a rolled upper edge, a cover for the outer drum, and sealing means for preventing leakage past said rolled upper edge from one drum to the other.

12. A dual container comprising an outer receptacle having a stop spaced from the top thereof, an inner receptacle positioned within the outer receptacle by said stop, each of said receptacles having a rolled upper edge, a cover for the container, and sealing means cooperating with the cover and said rolled upper edges for preventing leakage.

13. A dual container comprising an outer receptacle, a cover therefor, an inner receptacle nested in the outer receptacle and having a rolled upper edge, and a gasket interposed between said rolled upper edge and the cover for preventing leakage from one receptacle to the other.
